Abstract: A device for treating sleep apnea by discriminating between successive sleep stages of a patient includes a generator configured to produce stimulation pulses, a stimulator that receives the stimulation pulses produced by the generator and delivers stimulation to the patient, a sensor configured to measure a biological parameter of the patient, and a controller. The controller is configured to determine a state of the patient based on the biological parameter, perform a sleep analysis based on the state of the patient, activate the generator to trigger production of the stimulation pulses, determine a variation of the biological parameter subsequent to the production of the stimulation pulses, determine a response of the patient to the stimulation pulses according to the variation of the biological parameter, and determine a sleep stage of the patient based on the response.

Abstract: A device for visually scaring animal species, in particular bird species includes means for generating at least one visual signal including at least one image, varying in size over time, which simulates approach via an increase in the size of the image. For example, the visual signal includes one of the following images: eyes, a disc, and a spiral.

Abstract: This supersonic pulse flow device is intended to provide a technical solution in a number of fields where the injection of a flow must be pulsed as required by the process or in order to limit the power consumption and size of the pumping means. In the case of flows achieved by means of a Laval nozzle, it is possible to generate a uniform supersonic jet at very low temperature (currently up to 20 K), which is stable over hydrodynamic periods of time between 150 and 1000 microseconds. This device is aimed as solving problems relating to the use of aerodynamic tools in research and development and in industrial processes.

Abstract: A method for treating and/or ameliorating and/or preventing a disease or a disorder, the method comprising administering to an individual in need thereof at least one nitrogen heterocycle derivative of formula (I): The at least one nitrogen heterocycle derivative may also be used as a proteasome activity modulator in the manufacture of a pharmaceutical composition intended to prevent and/or treat a disease condition mediated by the proteasome activity.
